Ogrin's search turns up the following:
On Tryggvi: MW studded leather, MW rapier, MW hand crossbow, 2 potions, 2 fials alchemist fire, 1 tanglefoot bag.
On Kopasker: longspear, mace.
A search of the house reveals a simple, sparse living quarters and a well-stocked alchemist lab. Some of the components might be quite valuable, but its hard to tell. There's also some cash, about 100 gps worth. Almayce finally finds a spell book. It has all the zero level spells and the following 1st level spells: protection from evil, mage armor, color spray, magic weapon, chill touch, burning hands.
Kopasker cocks his head at Ogrin's question about poison. "I don't ask questions. The concave is a dangerous organization and I know Tryggvi works for them. He told me to give Krafia poison, so I did. That kind kills when drunk. I'm very good at making poisons. Perhaps you're interested. Leave me and my house. Return my spellbook. I'm in enough trouble as it is now with the conclave. I'll make you some poison and a love potion for this girl's boyfriend if you want. Then let me go. I'm going to have to leave this area."
