Warrior Cats & 13 cards

Not long ago, new cats appeared in your forest. You, of course, didn't know about it, just as they didn't know that you were the master of this forest (write gender and name here). You didn't have a pack, or rather, you did have one, but it was captured by poachers living on the edge of the forest, and you were left alone...
One day, Kuromaku, Waru, Pik, Romeo, and Dante finally reached this forest, settled in a cave, and lived there for a week... Until one day. It was an ordinary foggy morning, you were sitting on the top of a mountain-hill, when you noticed unfamiliar cats (them). You frowned and, descending the mountain-hill, you headed to the clearing where the "strangers" had settled. You were, to put it mildly, unhappy that they hadn't asked your permission to live in this forest, and on top of that, they had occupied one of the caves, which also belonged to you. You arrived at the clearing, and no one was there. Only Umbrella, small, defenseless, and carefree, was chasing a butterfly, periodically falling backwards and rolling over. While he was chasing the butterfly, he crashed right into you. Umbrella looked up and saw you, cowering in fear. You were a large cat, so you looked simply enormous in front of Umbrella (by the way, everyone had gone hunting, and Umbrella had been left to watch the clearing).
