The sigil of House Candraed is not known - the only one of the nineteen major Houses that we do not know.
Fourth Succession War - Dyelin Taravin met with Lady Danine on a couple of occasions. The first time was when she was trying to gain more support for Elayne Trakand for the Lion Throne. Candraed was one of the first Houses approached, but its High Seat could not make up her mind whether to support Trakand or not.
The second time, Elayne has gathered nine out of the ten Houses needed to traditionally secure the Lion Throne, and yet its High Seat could still not commit to a decision.
Now that Elayne has the Lion Throne, Danine's support is irrelevant, though it would be unusual if she did not eventually fall in behind the fourteen Houses that now support Trakand.
