when i trial by fire is put down are people able to teleport to prov within the trial influence?

On TbF area players can't port to Providence. Must go out from TbF area with empty inventory or build Leanto/Claim Stone to can port.

Kuku means, you can go outside of the TbF area and then there you can build a new Leanto and switch your HS there then you can port to Providence.
I guess you ask in reason for a TbF at your place to safe some items at another place.
Will you do this, be careful, because the siege guys will probably scout for such leantos.

Edit: ahh i read it wrong, you will place a TbF, then the guys that you will siege can do this, what i mentioned.
