The water dragon living in Terinyo, Blup, wants the player to locate his mother, the great water dragon Shyssiryxius. This quest is not technically assigned to the player (ie. it does not appear in the quest log) and there is no need to talk to Blup to receive the quest; however, both Blup and Tywat Pare suggest that you perform this task. Note that chaotic Chaos Knights cannot inform Blup of his mom's location, and so cannot complete this quest.
