so it appears there is no mechanic for them being "bound to their land".
I think story wise as a player archetype that would make for some bad exploration or adventuring limitations
what are your collective thoughts on this? I think treating it like the Tzimisce in Vampire the Masquerade or dracula mythos would be interesting. that they need to take x amount of land with them.
also I would love to see "sea" as a terrain type for a swashbuckling mummy
