Perception, DC 21: 1d20 + 1 ⇒ (7) + 1 = 8
Eleri looks on at the two men, both now in front of her, either draw weapons or dismount. Did they see something, or were they being cautious now that they were approaching the vista?
Perception to overhear Caladrius' whispering, DC 15 I guess?: 1d20 + 1 ⇒ (3) + 1 = 4
Well okay then.
Not knowing what the two are on about, Eleri simply stops her horse and waits. Annoyed at being left out of the loop, she silently vows to project her voice more during future lectures.
