Doomsday Fortress: Pyro

The nice Purple Fairy was about to send me off to another place that needs happiness when suddenly these huge stone monsters crashed and destroyed her and the Fairy God Mother's home. Among the monsters emerged a wizard, he was controlling them! He doesn't look very tough, and he was colorless, so I thought I'd give him rainbows and sparkles because he was really grumpy, he was hard to tame and I gave him the Lollipop and he was now happy, he ran off laughing and cheering. It was a delightful sight. The Purple Fairy took me away and told me that I have to go to the other places on my own. So I did. I wanted to fend off the monsters with her but she said she called for other fairies to help her and I have to do my job.

I went to places, there were critters who ran of in fear when they saw me, and I thought that they just need love and rainbows so I gave them. I couldn't even count how many people and creatures I helped.

I had to find a place to stay in and I did find one. Sometimes citizens would come to my place and ask for rainbows. It was fun and it made me happy spreading joy and laughter.
