1. I understand that Amku was either blocked or his AI was damaged. Perhaps he was killed and then healed, although that's unlikely.
2. Nefela may have been healed or guarded.
3. The Lizardman was almost certainly blocked, practically 100%.
4. Someone probably visited Ple-sen, and there was an attempt on their life, but it failed. It was a double assassination attempt. One was clearly physical, the other was with magic. The weapons for each of the characters are not specified, so it's difficult to say what their specific roles were.
Regarding the clues... There aren't many, since there were no murders. A Sword could have been used by an Adept or a Liathris. An energy bolt could indicate a spell cast by a Wizard.
That's all for now. Sorry if it's obvious. It's my first time. What's your opinion on this?
