Missing Unicorns

I ran into Zelda the other day while out looking for gemstones. She chatted me up about supernatural beings and whatnot. I suddenly realized something: if this is a realm of pure magic, where are all the unicorns? I asked her if she had seen any unicorns since we arrived and she said that she hasn't. I need to investigate this further and ask other townsfolk. I know she's getting worse as she seemed more depressed than normal. I spoke with Sabrina later about how she was and Sabrina said that this is the first time in weeks she's seen Zelda leave the house. She said she encouraged Zelda to go see a movie in hopes of distracting her over the loss of Hilda. While it did help for a few minutes, it's still not enough. I have to do something. I have to cast that memory spell to help Zelda forget about Hilda.
