Star Shield: a few questions

Hello fellow Andor enthusiasts!
I had two questions regarding the main Threats in this great expansion:
1. The Krahder:
He begins in Space 68, and moves at each sunrise to the next adjacent space with the highest number (so towards space 84). When the Krahder reaches Space 84, does he just stay there and "wait" until the end of the game?
2. The Water Monster:
Irlok begins next to Space 31 and advances 1 space per turn, following the numbered Spaces on the left bank of the river. He advances towards the sea (he turns left at the branch in the river). The heroes can only attack Irlok if they are standing on one of the spaces on the left bank of the river (Hallgard's green gemstone must be placed on the left bank to reveal Irlok, but the Heroes cannot attack him from the right bank). Have I understood these rules correctly?
Thank you for your kind help!
