Estinien pauses in Geralt's domain for two reasons: the first being that it's changed since their first foray into the horizon, and the second being that leaping into it is strangely like falling into a closed-off diorama. The mountains can't be as easily seen from the outside, but from within...

It's an illusion, of course, but it's one that appeals to Estinien's sensibilities. It's not incredibly unlike his own domain, though his remains firmly entrenched in spring and summer. He wanders around, unafraid, leaping into the Keep and then up on top of the central building. Eventually, he winds up at the front door, only to find a wolf waiting for him.

He's a little more cautious now, but when it doesn't seem to be ready to attack, he'll knock on the entrance doors. May as well figure out who this domain belongs to.
