Ledaal Katsu is an NPC in the Curse of the Blessed Isle.
Katsu is a prominent name in the Ledaal family, and renowned for his vigilance in the hunt for Anathema. He is a brilliant strategist who has been responsible for the downfall of many Anathema, amongst them several who have tried to raise an army of their own. He fought against the Conclave fifteen years ago and killed many of their members, mostly Dragonblooded and Lunars, but also at least one Solar: Daedalus. What most people don't know is that he is actually a Sidereal Exalted in the Bronze Faction, one of their agents to take care of the more troublesome Anathema.
Katsu is an elderly man turning gray who still looks as fit as in the prime of his life. He dresses in a warrior kimono and a blue jade breastplate over it.
Be careful when talking to Ledaal Katsu. He seems like a very friendly and understanding man, but his words are aimed at getting the information he needs from you. He actually loathes Anathema and the only reason he would form an alliance with any of them is if there is a bigger Anathema threat around and he could set them against each other.
Very little is known about what Ledaal Katsu can do, but Kaskovo says he wouldn't be willing to take him on if he had all the power of the Purpose behind him. He is an elder Sidereal, and any wise young Exalt would run for his life if Katsu would want to take him head on.
