Aesc is the rune of steadfast resolution and determination. It represents the ash, which in addition to being thought of as a representation of Yggdrasil, or the world tree; is also a firmly rooted tree that is hard to remove, whose wood was often used for weapons and shields. Thus Aesc is very much a rune of finding your place in the world and defending it with steadfast determination. Ac is one of the additional runes of the Anglo Saxon Futhorc, added to compensate for the phonetic sounds not originally found in early Germanic languages.
