Spirit of Rebellion
The gadfly dies, their souls burnt out. But the spirits behind them don't. So long as their cause exists, so too do they live on.
Muu took the words "alive so long as you are remembered: very literally.
The Spirit of Rebellion is comprised of all those who have died to the unjust systems they fought against, a ritual pulling all that is good and basing them around the Gadflies themselves. In this manner they spread along the memories to fight against the tyranny, the natural good they are made up of mutating those affected, making their brains hardened against evil. This manifests as a single-minded devotion to seeing that the Gadfly's cause is carried out. And all this power also manifests to give a Gadfly the ability to fight beyond death.
The Spirit of Rebellion modifies the Gadfly, appearing when they die. Naturally they are Rare.
Space-Time Environment Espy System
The STEER is created through forging Truesilver into runes of sight, observation, and various world runes along with time and others, carefully molded into a number of stone pillars and an altar. Through placing a number of lodestones throughout the areas, it is possible for Muu to use the STEER to observe the movements and concentrations of evil across the lands. This can be used to determine movement patterns ahead of time, and even use that info to deploy Unique units in opposition to others. Nur-Carok stands out as a beacon of darkness, though other unique units are generalized. The STEER is capable of counting how many of such signals exist within a given time, giving an indication of any new units that are created. Due to the observation/effect clause, this can only be noticed after they are created, rather than before. Sadly as infrastructure, it can only be used at home, so any changes that occur during the battle or in cities will be unknown. Though having a proper overview of what will happen gives you the ability to change it.
tl:dr: Allows us to count the number of Heroes the opposing side has, as well as see where they will be deployed. This can be used to assign a hero to counter another hero (semi-randomly). Nar-Carok is Evil enough that we always know where he is, so can assign units directly to them. In addition, it gives our forces an advantage of info on what the opposing side will do in general, granting an advantage due to foresight. It is not self-updating(since only Muu can use it at home base), so it's information will degrade quickly when we go against what is seen. (Does not actually give us a look into the demon's thread for the first part) Is mind-breaking enough that no mortal can use it.
Blessed Sea Salt
Saltwater is dumped into a pool within the Forge of Cleansing and left to sit. Solids fall to the bottom while water rises to the top. The result is a lot of high-quality sea salt.(and other things which get picked out of the final product) Due to being within the forge it also absorbs trace amounts of good, which acts as a slight counteragent to evil. Useful for everything salt is useful for, including keeping out evil spirits and preserving the dead.
Community Services - Remembrance Ceremony
These "Masters" turn what should be a time of mourning into a time of wrath. Funerals should be times to remember someone, not be twisted into a mockery of who they were for some nebulous purpose. Enter the Community Services, an Outreach program to help others less fortunate. The communities take on the burden of funerals, gathering many people and using their wealth to ensure that the dead will be remembered for who they were. A number of speakers are chosen and imbued with a spell-work to pass on this thought, that those that die are not truly gone so long as we remember them in our hearts and souls, and through doing so bring peace to the bereaved. These funerals also include some simple food and drink laced with the worms of Muu. The good imbued in the funerals will keep them fed for a week or two before they die out, giving them time to mutate others to the Community's service. And perhaps most importantly, helping the bereaved is a profoundly good act which raises up those who perform these Remembrance Ceremonies, instilling in them the noble good that marks them as pillars of the community and a voice to rely on in times of doubt. (Uses Wealth Token to help the bereaved families in their time of loss. While the Remembrance Ceremonies are simple, the coin helps the families who have lost one of their own, and encourages friends to also help them.)
