Alright, a few comments on the submitted characters
Tider (optimumsquare): According to the Player's Guide (pg. 8) elves are pretty rare in Korvosa and most of them live in an elven enclave full of diplomats and sages; Tider's family would have both the motive and resources to look for him, so you might want to make him an orphan. Also, given Tider's facial features (and ears), Lamm would be aware that he's an elf, so beating him up for creepily not aging sounds a bit off. The Tortured background says your character was beat up and left for dead after making one too many errors, so I'd suggest to revise that part as "Lamm beat him up for failing his overly high expectations". Elves are a rare catch for him, they can infiltrate certain areas (such as the elven enclave) without raising much suspicion and should be good with stealth, picking pockets etc (because Dexterity) so Lamm expected much that Tider couldn't deliver.
Sezuram (Silim): Half-orc and sorcerer is an interesting combo, especially with the rest of the build. There's no character background on the sheet, but with Orc bloodline, Magical Lineage and that Bloodline Power, I'd guess he's the offspring of a (quite powerful) orc shaman of sorts. Perhaps the mom was a member of the Shoanti, which would also explain the Sacred Tattoo (because Orc tribal tattoos on a City-Raised character don't make much sense). Last but not least, I'm curious about the Framed (Dropout) background; the Acadamae is strictly restricted to Wizards and actually goes to great lengths to propagate that magic without rigid training is dangerous, which of course gives a bad rep to sorcerers (Player's Guide pg. 11) so unless you want to change it, the Dropout background could refer to a religious order or a certain social group.
Iroboang submitted an incomplete tentative character sheet that also says "sorcerer". Since he talked about a "Caster" earlier and Silim submitted a sorcerer character first, I was thinking we keep Sezuram and Iroboang might wanna switch to a more cleric-y character to fill in that gap. Up to you two, of course.
Still waiting for Vulco1's character.
