My regrets, but I must amend something from the last thread.
To the Solistarim - you are not able to gate into Realmspace with your elite force, then run out, because yes, Realmspace has a powerful border guard ... the moment you try to Gate in, you encounter them.
Of course, they might let you pass, if you are there to fight the Legions of Vecna, but that is up to Reprisal and Forrester.
My regrets, William, but the great Host of Kevellond, as it tries to enter Realmspace, runs face to face into the Border Guard.
Unless Reprisal or Forrester give permission, that is as far as your force gets.
Since your force is there to fight against the Legions of Vecna, they may allow you through, but that is up to them.
The army of Turrosh Mak was able to reach Realmspace, because of Vecna's Gate (Vecna alone being able to breach the Torilian defenses.)
It is now doubly impossible for Turmosh Mok to communicate with his general and his force, much less order them to come home.
