I was deleting junk email yesterday, and I noticed a little theme among a few messages...

Significant letter. You need to read.
Momentus message. You require to read.

Subject: Yet too late; unfortunate for a left Lundin Crast, his uncle's eyes were
Message: yet none I don't wish king stopped, Randel, your own By influence,

Please, tell me what it means!
