not to get into it and i have better things to do with my time than nitpick fics other people are clearly excited to be writing but like sometimes i wish people would just do a quick wiki search before they decide that the presence or absence of something is going to be a major plot point.

petty level of this grievance: admittedly opals are not super important in asoiaf but they do show up several times. fire opals too. a quick check of search of ice and fire could have told this author this before they made 'character coming in from [redacted crossover setting] has Never Before Seen type of jewel! this is super valuable bc they dont exist on planetos and selling these will get this character Set For Life!' especially given that said crossover setting really does gave several suitable materials that genuinely dont exist in westeros.

low-moderate level of this grievance: treating lions like a mythological creature thedas only has bare rumors of, and then having the inquisition heavily lean on an existing lion-based title for [redacted crossover character you can figure out the identity of by using your brain] when lions are literally the heraldic animal of the ruling family of orlais. doing this lionhype thing would therefore obviously have some political consequences. instead something that could have lead in to an interesting plot angle is simply an infuriating nothing.

high-moderate level of this grievance: if you are setting out to write a self-declared uplift story using a books-only setting and have put enough research and effort in to draw up reasonable, detailed maps based on known canonical geography and territorial claims of a region, you have little excuse for not knowing that there is, very intentionally, no mention of potatoes in the series (this series where food is often deeply important on a material and symbolic level, to the point where one of the common talking points to razz on the writing is 'sudden, very detailed description of food that stands out from the rest of the scene'). uplift stories require some thought as to what would or would not be available, where/how some resources could be found/built, etc. if westeros already had potatoes as a normal staple crop the situation would be massively different! i know you know this bc your character outright ruminates on the historical impact of crops spreading between the old and new world. if mitigating the famines is a major plotline in your uplift story why wouldnt you make a story beat from it? or at least just have the potato discovered and implemented? the classic excuse of 'oh turns out it originates from sothoryos and only a few groups are willing to broach that place looking for goods' is right there! why would you make it come pre-installed?

major level of this grievance: [insert comic panel of that genie saying "[REDACTED]" here lol]
