While getting back into the rhythm of his pre-adventurer life Mason starts looking in the assassination attempt on Amelia's life and find out who put out the contract and why. He knows full well that Arlo is resourceful enough to find the answers on his own but the timing of when it happened and who saved her continues to knaw at him.
Reaching out to "legally flexible" contacts he's made since joining the group, he offers 200 GP for information and proof of who put the hit on Amelia.
Mason doesn't continually talk about his adventures but every now and then something reminds him of what he's done and he does feel sad.
He writes a unsealed letter to his friend's sending it to Fip's parents knowing that they would get it to him and the others.
"My dear friends, I'm sorry I left so suddenly but I hope Scree filled you all in on the letter from Amelia. I love her deeply and love all of you, yes even Erik to a extent. I'm not sure if time will permit me to travel with any of you again but I pray that you all will be stay somewhat safe in your future travels. I had a idea for the business that i'll hold on too til y'all can see it and give your opinion.
I can't see my life without her and after that trip to the future where I find Amelia dead I find it hard to be too far from her to keep her safe. I did put the idea out there for her to join us but she's not interested in adventuring and I don't blame her but she hasn't seen the look of relief on people's faces after we help them no matter the outcome we give people a since of closure.
I don't know what the future will bring but I'll cherish the deeds we've accomplished from possibly putting a end of the Fungus disease, which I haven't seen or heard of any new cases since we killed that creature or stopping the Great Worm from being freed (I'm still mad I lost my portable hole.).
Please look out for each other and when in Isondale please come visit me."
Your friend,
Mason Farson"
Mason just folds the letter realizing he's gonna be late for a appointment if he doesn't hurry so he asks Amelia to send the letter for him along with 25 platinum for the group. (If Amelia reads the letter is up to you Greg)
