For this challenge, we are given a jpg file.
Analyzing the file, the symbols tell us that they represent an alphabet/substitution cipher. The hint tells us that it is another alphabet of some sort.
Doing some research, we discover that the cipher is using the Hylian Alphabet from the video game series, Legends of Zelda.
Translating from the Hylian Alphabet to English, we get riftctfsurvivalofthefittest.
