Sereth:
Hey GM, how much about Daleks -does- Sereth know?
Specifically: Does he know about the robo-zombies from Dalek Invasion of Earth? From what I recall, they haven't really been mentioned since, but it seems possible he might think of them at this point; if he'd heard of them.
Hm. If you want, you can roll Ingenuity + Knowledge to get your general level of Dalek lore. This robotization schtick seems to be a thing they come up with occasional variations on (way more often than DIoE if you roll in the vague amalgamation of non-TV media) and is probably no more obscure than what Tricky would give you.
And in fact since you brought it up I'll give you that bit as a freebie, but the roll would still be handy for other things.
