Valrieth will largely be trying to keep out-of-sight behind Zylo and Iali as they approach the guard tower.  She hopes that they don't have to kill the bullywug(s) on the platform, but that probably means capturing him or scaring him off before he sees her so that he doesn't raise an alarm and alert all of the other bullywugs in Downfall about her location. 

Zylo looks for an entrance to the building, "Right through the front I say, then we can lock or bar it so that we have time to deal with those inside and then you can get some rest." He says, over his shoulder as he moves. Once he finds an entrance, he hesitates, "If it's locked, you know what to do Iali." He then tries to open the door.

Iali keeps an eye on the figure at the top of the tower. Does it seem like they have been seen?

As they move towards the entrance, Iali begins to prepare the Knock spell, in case they need it to get through the door.
