Jar of Octopus Venom; 4 / 5 uses remaining (45)
Uranium pellets (x20) (25)
severed arm of tom roper
hanging basket full of forgetmenots
barbecue fork
any whatever money for the difference

The merchant agrees to this deal, he likes this so much he gives you a pink metal token which he assures you will please you greatly when you use it, apparently they are really wild. What exactly remains a mystery.

The party walk away satisfied, but as Nimeria suddenly tries to talk to Sarah somethign strange happens; Sarah replies Forget me not, Forget me not, Forgoet me not, Forget me not

The party realise that they have fallen into a horrible trap.

They run backtowards the merchant, knowing that they must get those forget me nots back.

The stranbeg beign smirks and akss for 1 million sivler coins.

Nimeria unsheaths his sowrd but the boar headed creatue just shakes his head and sighs and thorws a smokeball to the ground. When the smoke clears the perculiar trader is gone and all Sarah can say is forget-me-not.

What will you do now.
