Initially, i created this mod for my own server (Havoc in Fliegenland), where i play with my family. But, may be someone can find this mod useful too.

Mod adds a way to craft trader summon doll (trader sumon item from creative tab), so, you can create "trader district" for you village or town.

• Kill enough drifters (1% drop chance), or bears (3% drop chance) to obtain SoulShard. (you dont need to loot mob with knife - item always drops on ground, if you are lucky :) ). BTW, you can use soulshard as bright, stationary source of light.
• Visit to your local traders, and buy "Trader summon contract". Yes, it is expensive (~100-200 rusty gears each). Each trader sells corresponding version ov contract - i.e. artisan trader sells artisan summon contract, luxuries trader sells luxuries trader summon contract e.t.c. Only exception - treasure hunter. He can sell you treasure hunter summon contract and light trader summon contract. Light trader are guy, who can sell you this beautiful "Creative light" and "Creative glow" blocks. And will buy from you any crystalls you have.
• Craft trader summon doll, using soulshard, trader summon contract, and some trader-related items (including decent amount of rusty gears, and one temporal gear. Your trader needs money to create his own busines, and something to create his spawn point :D )
• Place your trader doll where you need this trader.
• Woila. You have your own trader in your own settlement.
