A bijili (pronounced bee-JEEL-ee, soft "j") generally refers to a power source or storage in Tradertalk. It can also be a magic knot tied by Trader mimanders. In it the mimanders trap winds that can be released later to carry their ships when there are no normal winds at sea. Traders also sell these knots to other sailors, although they are quite expensive. They don't sell them to pirates, however, as this is against their rules.
