I have now read (well, skimmed at any rate) all of the campaign thread since my character's introduction, so I believe I can now more or less resume RP as though I had been following along. I've left Relgar's last post, in which he comes to himself and is confused, as I wrote it before doing this back-reading; the Memories link is a reminder to myself of how I've played him in the past and what he's been involved in.
Relgar has just been revised from his max-human intelligence of 18, into the normally impossible 20 which he achieves by virtue of his Paragon status (he remains a 5th-level wizard, as he was before being revised into a 6th-level character, but gains an immense number of Skill Points in the change, as well as his heightened intellect; since he has no Familiar, he loses nothing in the change, and I may well give him an Alternate Class Feature in exchange for the lost Familiar, which can happen when he actually reaches Wizard 5). In view of this, I figure that it will take him only a moment of befuddlement to put together what's been happening around him, while he was focusing on his work and not paying attention to his surroundings - he heard the conversation around him, he just didn't listen to it, if you follow that. So my next post will be where he makes it clear that, in Sherlock Holmes / Iron Man fashion, he's picked up the gist of what's going on, despite his apparent lack of involvement.
I'll also be addressing the character change, through the vehicle of the problem he was solving in-scene, although he's still going to be at the WBL of a level 5 character, and have knowledge of only three "Grade" 3 spells. His next level will be a Geometer level, so I'll start making allusions to the abilities he will end up having once he fully qualifies.
