Tempering, in the context of wrought iron and blister steel produced from a bloomery, is not annealing. Annealing is the process that happens in the game.

So let us delve into HISTORICAL tempering processes. Lots of terms were used, certainly. Lots of regions, many eras. Vintage Story is a weird pre-steam steampunk thing, so no use there. Personally you should maybe drop the term Tempering. If you used it at all, I would apply it to "quenching", as HISTORICALLY it has often been the term applied, and generally the whole process is often referred to as tempering. This is also the common perception, despite there being too much complexity in the modern era for just two terms. You can see this in references to the "temper" of the end product, where it is referred to as both the hardness and toughness of the product. What you are calling "tempering" in the game is actually annealing. Modern tempering has nothing to do with it, and that term was only used rarely in the past when ONLY associated with high temperature slow cooling. It was most often applied the other way around. Say "quench" and "anneal", and state how one is associated with toughening and the other with relaxing the metal. Of course thankfully the gamification of this is no where near as disrespectfully bad as the deal with the sailboat. It could have easily been so good, but it is soooo bad...meaning disappointing. Please just remove the silly attempt at a squaresail that goes anywhere and uses reefing as a throttle control and just put in a magic gearbox motor thing...or do it right.
