Finn was standing on top of the mast now. Looking around,on top he had a great view of the confrontation. More outlaws came in, but it seemed they were the last, for there were no further ships in sight. Finn counted three more magicians and seven more heavy armors. He didn't know how strong the magic wall of the defenders was, but he doubted it will last long. And the magical armour of the attackers was a great deal of a nuisance. For a moment he was trying to find a solution. Then as one had formed into his mind he imagined it, how it would work and how to set everything in motion. He hid back into the core of the mast where he was invisible. 

He opened a small vile around his neck. The aroma of the vile could only be sensed by Reva and it attracted him far and wide. Moments later Reva was at Finns feet his antennas twitching with excitement. "Take this rope and spread it around the floor as close as to the enemy's as possible. Then run to the mage who made the shield and give him this note." Finn tied one end of the role to the mast the other to one of Revas limbs. And pushed the letter intob Revas mouth.
