I originally ran this as a semi-solo caster, but I finished in about 45 minutes, so I guess it's a speedrun. I could shave off at least 10 minutes easily due to mistakes. Also, I didn't have any notes or guides, I just went off of memory. I recorded this on Linux using Steam's built-in recording. I have no idea why the cursor is stuck. It wasn't when I was playing.

Start time (leaving the Adventurer's Guild) 1:03 Finish time (ending the final fight against Mangar) 47:43 Total run time: 46 mins, 42 seconds. Start at 001:03 and end at 47:45 (when I re-enter the Adventurer's Guild), for a total length of 46:42 if my math is right.
