Suusad

Could you clarify what "suusad" refers to? Is it a place, a person, an organization, a language or concept, or a fictional work? If you have a source or context (region, field, time period), please share it. I can then write a concise, neutral wiki-style article under 300 words. If you’d like, I can also create a stub for a fictional concept named "Suusad" and clearly label it as fictional.
