        doGiveGemsBackTwo(cid)
        doSendMagicEffect({x = tp_pos.x, y = 1039, z = 8}, CONST_ME_TELEPORT)
        if(fromPosition.x ~= 0) then
            doSendDistanceShoot(fromPosition, {x = tp_pos.x, y = 1039, z = 8}, CONST_ANI_ENERGY)
        end
    elseif(aid == 2004) then
        doCreatureSetStorage(cid, 15180, 0)
