I believe there are two possibilities as to why the hand assuming it's controlled by or is Xau-Tak. One being that the temple is built on some sort of conduit which allows Xau-Tak to interact with Gilenor kinda like the amulet from "The Chosen Commander" series. The other being that the temple the portal is in already seals it off from the outside. So in a sense it's outside the edicts.
I'm sure there will be answers for when we revisit the temple or when we know more about the Dragonkin language. Especially since we know the murals in the temple tell us that the Dragonkin were attempting to perform some kind of experiment on the portal and by extension the hand and black stone. Possibly in attempt to find a way around their bond to the Stone of Jas. But it's clear they had to abandon it and seal it off because they were unable to control it.
As for Xau-Tak's identity well I believe he's more likely a being similar to the Prehistoric Abyssal creature we fought during "Heart of Stone". Which could mean he's from a previous version of the RS Universe. This could explain how he has powers we haven't seen from other beings or even other gods. As we know he was able to communicate directly with us during the quest and he has even communicated with us across space and time.
So may not even fit on the current tier list. But given what we've seen from him so far he's probably around the tier 2 mark in terms of power.
The statement below is false.
