Silent watched the battle from above. She sent down her blue swarm to help watch over their own ship. When a pirate managed to make it over. The carnivorous butterflies immediately attacked. The ranged attackers knew that their spells wouldn't hurt her pet and the flutter blue mass was an indicator of who they should target in the midst of the chaotic battle.
She wasn't only focusing on their side though. Her arrows began to rain down on the pirates who took cover from the lateral attacks that were flying from deck to deck.
They may be able to use barrels and crates to hide from the attackers in front of them but they couldn't stop her attacks from above.
She kept most of her attention on Lucan, whenever he was about to be surrounded by three or more, her arrows would fall and help him finish one of the enemies off if they were close to death.
