This part story includes some unique Irish terms. I hope you'll find this glossary useful:

Iomaire Draíochta – it's the magical ridge where warlocks with Sentinel powers live and where the warlock children are trained.

Caomhnóir – term for a guardian of the spirit world and identifies warlocks who can communicate with dead spirits. At the moment, it is believed that Sazith and Raelyn are the only warlocks alive who possess this gift.

Na Miodóg - name of the magical soul dagger and the only weapon that can kill warlocks. It's hinted that each Sentinel owns one, but that Marush's dagger was stolen from him by his mother Kaleidopae.

Cloch Draíochta - the magical stone that, together with the special metal of the dagger, gives the Na Miodóg its magical powers.
