Sagwi, also known as the The Principality of Sagwi, is a member state of the United Territories of Sky Haven. The principality is believed to be founded on a tooth of a tiger. Prince Calvin of Tiger Tooth is the head of state of the principality.
The Allium on the flag represented Prince Calvin's ancient clan name "Chong", which has the cantonese meaning of green onion when pronouns in English. The designation of "Green Onion" was widely known before Prince Calvin's reign at Tiger Tooth.
