—Crossroads of Twilight, Chapter 19
Strength and Abilities
Being a Sitter in the rebels Hall for a while means that Escaralde is also a high ranking sister and a strong channeler by Aes Sedai standards. Thus she has the strength needed to use the travel weave.
This is not confirmed by "The Wheel of Time Companion" where her level of strength is described only as 23(11). But this is probably a mistake because ten levels below the strongest Sitters would mean that Escaralde was a too weak Sitter compared to them.
Escaralde's true level of strength can be guessed by the time she spent as Novice and Accepted which was in total seventeen years, roughly the same as sisters that are at level 20(8), in fact the time spent in training usually reflects the strength of an Aes Sedai.
She is also stubborn and would refuse to believe that she could not do or learn anything, until she proved it to her own satisfaction. She insisted on trying to learn to make ter'angreal despite lacking the sufficient strength.
She is from Far Madding. Escaralde was born in the year 927 NE and went to the Tower in 942 NE. After spending eight years as Novice and nine as Accepted she was raised to the shawl in the year 959 NE.
Although Escaralde wanted to learn how to make ter'angreal, she is not strong enough to be able to do so.
