Eabhadh

With Eabhadh we find something interesting: either it is meant to be Ebhadh Which means Aspen ( a tree already covered) or it means koad. Since we can assume the author was consciously thinking when he wrote it, it is probable he would have meant a different letter (otherwise he would have used the same letter twice).
Dealing with this challenge several authors came up with a suggestion, rather than being a tree, the letter stands either for a grove or a salmon.
Which would give:
Divination
Central balance, infinite possibility, sacred place and council.
