A Hawker (also known as a Roadside trader) is a vendor of merchandise that can be easily transported; the term is roughly synonymous with "peddler" or "costermonger." These traders never liked the competition with surrounding traders while working in bustling towns, so they decided that the best way to increase their profit was to remove any competition. However, due to their lack of toughness, they decided that they would instead remove themselves from the competition since this option didn't require any brawling, and they thus set out to lead a nomadic lifestyle. They now roam the land of Godville, setting up their tents wherever they have detected gullible travelers passing by.
Hawkers carry a lot of heavy merchandise around with them so they prefer to appear out of nowhere at unmarked milestones so that they don't have to drag their stuff around for too long. Hawkers are greatly hated by heroes and gods alike for when a hero stops by at a hawker's shop, it is as if they are stopping at a small town. Most are unavoidable because not a lot of heroes can stand up to the hounding of a desperate trader, unless they carry over half their inventory full or are not too injured so they can go to a town to heal, should they be compelled to, anyway. They would only appear once in-between trading in towns, to give the heroes a chance to visit a tavern of their choosing to offload their pockets full of gold.
Heroes who stop off at a hawker's tent do not pray, are not healed (though will buy healing supplies) and worst of all, can be idly stuck chatting with the hawker for around half an hour (even an hour in some cases,) giving a wandering master enough time to get the hero's hard-earned gold coins on a measly skill upgrade. Needless to say, gods do not appreciate their time and/or effort being wasted like this. The only consolation is that a hero lucky enough to be taken in while their inventory is bulging with loot can expect to make a lot more money than usual, as if they visited the town of Tradeburg. Heroes also can take advantage of the hawker's brilliant bargains, getting discounts on equipment and healing supplies, but not on skills - that's not the hawker's expertise.
Note that like regular traders, they won't buy tribbles off of heroes, but unlike the same town traders they won't buy boss-monster parts that could be used for the hero's lab, regardless of whether he has one or not - which is superb after one too many complaints of having their wills being crushed as it never made it to their creation of their very own boss.
Although it's rare, but some days could have the roadside traders go on strike, meaning they will not appear at all outside of towns.
