I must say, I love HP&tN20. Between it and the Order of the Stick I fell in love with primary casters (particularly wizards) before I ever read the Player's Handbook. It's been bugging me though; Which book says what happens to the familiar of a dead wizar

It doesn’t say anywhere what happens to a familiar whose master dies.

I looked and looked and looked. If there’s any clue, it’s in a Dragon Magazine or something similar. So… I basically made a list of possible options and chose my favourite. Here’s what I came up with:

-The Familiar disappears and the Wizard needs to summon a new one after being Raised. (This sucks, as I like Mordy, and don’t want him to suffer sudden existential failure like that)

-The Familiar goes on as usual. (This struck me as probably the most likely to follow the rules, but still weird—why aren’t there dozens of familiars kicking around of dead wizards? Actually, that would be a really cool detail in a campaign… the familiar of a long dead, all-powerful wizard who is a powerful entity in its own right now. Oh man. I just realized the potential of how cool that NPC could be.)

-the Familiar dies and ends up in the afterlife as well (I toyed around with this idea, but dismissed it. Milo never really had any time alone in the whole series, and I wanted to see what happened when left by himself in the afterlife).

-The Familiar reverts to pre-Familiar animal state as the Wizard’s power vanishes. This is the one I chose, because it struck me as the most ‘plausible.’ Also, it had good story possibilities.
