Is there other magic in The Destiny Cycle?

Aye, Druids use Elements (Earth, Air, Water, Fire, and Spirit) as powers that they manifest in the physical world; Sigils are patterns, usually in the form of a tattoo, that amplify an Element or combination of Elements. Elements and Sigils are consider "hard" magic, because the are rules and limitation. The "soft" magic in Destiny Cycle is Badb Catha's is the mysterious "dark matter" that powers balefire and "shields", which cancel each other, as in only one can be used at any given time; there's a cycle time between them of ten to fifteen seconds, where a weapon that casts balefire disableds shields, and when shields are active, balefire cannot be cast. The void and sight tap into time-magic via the Stone of Destiny and the Cycle of Time. This is clearly "soft" magic of the Tuatha gods.
