Here's the thing though, merchants seem to want half the perks without trouble, I haven't seen a single merchant that sells in the Outskirts, lugging along his 1k plus in weight of items around when he dumps it on the floor. The closest I have seen, would have been Griswold, carrying around his chest, with an actually banner for the company. That in my eyes is immersion and is what we need. IC opportunities pop up -everywhere- it's just many people don't try and act on it. Also, player owned Tavern and store.. there is one reason factions are good to join on this server, immersion and perks. Vardo has job security of a decent degree and as such, has done most of the groundwork needed. WK has their own building, people could approach the leader, see if the House could be used in the "Kitchen" room, as a random assortment of boxes and stock, there is also the Drain for those who want to do business, and the rules of thievery and fighting are surprisingly tight, meaning your wares are safe, until you step out of the Drain with them.
There's plenty of places to make a mark, there are abandoned houses, churches, etc all over the place that can be used as an aspiring player-factions shop, the only problem is that people don't seemingly go for it. Sorry if some of this doesn't make sense but I am typing it in a hurry, what I'm trying to get across is, scour the server for neat places you can use, talk with a DM or two, find out things about the place IC, raise substantial coin, or IC info in exchange for keeping it safe, etc.
