My characters are coming into COS with. A sun blade already. Help! So my dnd group always switches around dming games so I will run a campaign for about ten sessions and then the next guy will and so on. I decided COS will be our first big campaign for the group however I have run into a problem.  In the last campaign we just did my buddy gave the sun blade as loot (not knowing that this is a huge part of COS) to one of our characters and I don’t know what to do. Do I somehow make them lose it? Do I just work it in? Any ideas would be great
