UOG: Demise

Since they don't recall with the player you must gate them around
They will not disappear as long as you stay on the same facet with them if you recall away. If you recall to a different facet they disappear
It works this way sometimes and other times it does not work that way
I am in Malas showing I have 3 followers. That is the allured arctic ogre lord I recalled away from in Minoc. I recall back to Minoc and it is there. Once again I recall to Malas but this time the arctic ogre lord disappears
