This Time's Sea of Time

My main server was fine since I had characters I could bring, but... I didn't have any characters I could bring to my sub server, so I've been stuck on Stage 20 since day one until today, day three. I got some advice, so I'm going to try again, but I feel like I've fallen so far behind that I can never catch up 😇 I finally cleared Stage 20 and made it to Stage 23. What a relief.
