Kaboom, the Wanderer is thousands of years old, and extremely powerful.
He is not fooled by the simulacrum.
When he sees that Thayadon is trying to fool him, he just laughs and dismisses the simulacrum, and does not even speak to it.
However, when Anabstercorian (who is Torilian) arrives, the Wanderer sees him, knows him for who he is, and he knows his history.
The Wanderer, if it is possible, becomes more angry than he was before, turning red.
And then he speaks ...
Anabstercorian of Toril, you are an escaped convict, and the noose of the Torilians awaits.
A tight noose, and a very permanent one, I would daresay.
Do not presume to lecture me on whether the Elder Ones may or may not be summoned ... I know much more concerning this matter than even you, illithid.
In any case, the CHANCE that those who plot this summoning will succeed exists, and if there is any chance at all, then that is too much of a chance.
Someone must speak for Oerth.
Do you presume to speak for Oerth, illithid?
You are Torilian, and you have already seized power from one of our own great Powers, and made them yours.
ANOTHER CASE of Torilians interfering in our world, our business.
What gives YOU the right, illithid, to walk into our world and start saying that this will be like so, and that will be like so?!
Yet this you have done, and all the Solistarim bow to you!
To you!
(He looks so furious, he looks like he's going to have a heart attack. He turns scarlet with rage.)
A Torilian illithid enslaving the people of Oerth!
A Torilian illithid, walking over our people!
I will personally see you destroyed, Anabstercorian.
It will be a slow and devastatingly painful death, I assure you!
You will be dissected piece by piece, while you watch.
