I like it, this definitely provides a reason for traffic to be passing through winterspace. a port that needs room for 50 ships (not including ships that land on land, such as their own fleet of wasps) is going to to involve a lot of ships traveling all over the place to bring them what they want. one thing i would consider adding: if this is the primary port for the planet, wouldn't that suggest that goods are commonly brought there, and then transported by other means to the other cities? (at the very least, the ones closes on either side, i would think). if so, that would imply they would need an area for ground-based transport as well. or perhaps a canal even (that would involve a lot of labour to build of course, but then, the entire planet speaks to a race having terraformed it to their desires. and who knows, maybe the lords of the various cities don't mind investing that amount of labour either).
also, given a ruling class of mages, it might be worth mentioning that some of the trade can be for more unusual things as well
anyways, as usual, proofreading:
Tyme, paragraph 1: "Tyme is the premiere ports..." (one of)
"The city docks are at the bottom of the holes." (either bottoms or hole, i think. based on later stuff, bottoms)
"...in almost as quick of time." (don't think quick of time is quite right. 'as short a time' is what i think this should be, but i'm not sure what you intended)
paragraph 2: "Of the cities of Radole..." (i think this isn't actually wrong, but my personal preference would be 'Of all the cities')
"...and the people the least likely..." (are the least likely)
paragraph 3: "It occupies a very large slope rising gradually towards the mountains on the Nightside, affording the most sunlight to its citizens." just a thought, but you could have a "slums" area where the undesirables are stuck living in the shadow side of the crater, with no sunlight. or not; plain old ordinary crushing poverty is probably dark enough figuratively without adding literal darkness. or of course, you could otherwise make use of it; perhaps there's a community of some race that dislikes bright sunlight (there are several that take penalties in bright light). perhaps the thieve's guild has a few hidden warehouses dug into the dark side of the crater, knowing that it's both right next to the city and yet not populated. on the other hand, glowmoss is a thing too
Hrull Manor, paragraph two: "The Manor has at least six levels. Observant readers might recall I mentioned only three stories above..." (this shouldn't actually seem that weird, he already told us most buildings go underground... the precise nature of these particular stories is certainly unusual, just pointing out that this shouldn't necessarily cause any raised eyebrows initially)
"The Hrull family crypts is located..." (crypts are or crypt is)
paragraph 3: "...many guest chambers two separate kitchens..." (missed a comma)
The Junction, paragraph 3: "It used to be might lighter..." (i think might should be mite, and the expression is usually 'a mite'; google it and expand the definition that shows up to see what i mean
)
"Ambra will certainly vouch for me! ’" (the floating apostrophe at the end)
Umberdeep Dock, paragraph 1: "...its walls are lined with reinforced walls of stone." (you know me and repeating words. i can't think of an appropriate direct replacement, but you could alter the sentence a little. for example: "...its walls are reinforced with stone." or "...its walls are lined with stone."
"A lake and piers at the bottom allows it..." (allow, i think)
"Dock rental rates at a flat fee..." (are a flat fee)
paragraph 2: "Warehouse space can be rented at a rate of 1 s.p. per ton per month..." (this is not strictly wrong, but i feel like i should point out that the merchant kit for warriors found in the spacefarer's handbook allows a merchant to trade for 1d6 gp per month per unit of goods they have... with one unit of goods taking up 1/10 of a ton. that's a minimum of 10 times their investment if they only have one unit, up to minimum 100 times their investment if they fill it, which seems a tiny bit generous). of course, on the other hand, that kit was also written by a person who in one place says they get their starting merchant goods in addition to their normal starting money, and then later reduces the amount, so... YMMV on that one i guess
)
"Steel bars from Krynn are stored near shadowbrough timbers from Toril." (perhaps it's just me, but the idea of krynn exporting steel to anywhere just feels weird...)
paragraph 3: "The ramp circles Underdeep..." (Umberdeep)
The Wasp Nest, paragraph 1: "...so keep get what ye need..." (no keep)
Shops: moreso than usual, i would say that the kraken might want to point out that in a city with 100,000+ people, with docks for 50 merchant ships... well, you're not getting anything even remotely comprehensive here
The Scroll Caddy: "Tucked in the corner of Gorm Street and Bakers Street..." (Baker's)
"Prices are reasonable and a good way..." (are a good way)
Redd's meats: "Barrels of hardtack is also available..." (are also available)
Trill's Tallglasses: "Row upon row of wine racks holds..." (hold)
The Fat Giant: "...that serves a host of hot, spiced meats, warm breads, and..." (personal preference strikes again! specifically: because you're making a list, i would be inclined to remove the comma between hot and spiced. i don't think it's wrong, but it may cause a moment of confusion as people try to figure out how they sell hot
)
The Blind Blink Dog: "An unremarkable tavern with creaky, ancient furniture and serves..." (that serves)
A Gentle Spring: "...down the hall pass the guest rooms..." (past, not pass)
"for rooms that average to slightly above average." (are average to slightly above average)
Wormholes, The Place, paragraph 3: "Beyond the taproom is three round..." (are three round)
"The lantern can be shuttered to the comfort of the occupants." (doesn't quite sit right with me, i think mostly because contextually there can be only one occupant for the respective lantern. assuming that's what's bothering me, perhaps 'occupant(s)' would resolve it... but i'm not sure that's even necessary)
"...as well steam rooms for relaxing." (as well as)
on a side note: it feels weird to me that the place has continual light lanterns (which i'm presuming are being artificially dimmed, because it's normally explicitly bright) in each bedroom but doesn't seem to illuminate the taproom very well, which would be a simple matter of using continual light lanterns that are just not dimmed
Wormholes, The Prospect: "The staff is competent..." (are competent)
Wormholes, The Provender, paragraph 2: "...a wide variety of liberations available..." (libations)
"...from ale and beers to..." (ales and beers, unless you mean only one kind of ale but many kinds of beer)
"...save for Elverquist out of Evermeet, which the bartenders have a steady supply." (of which the bartenders)
(incidentally, given it's a cave, being popular with elves is slightly ironic
)
Wormholes, The Prices: (would make sense to list a price for Elverquist, considering they're explicitly noted for that
)
