Slaanesh - Pleasure, Obsession and Excess: Many of the factions of the Adeptus Ministorum and Adeptus Terra embody restraint and denial of base enjoyments. Knowing that the easiest path to corruption for most Imperial citizens is simply freedom, they impose harsh rules and ultimately a harsher existence on their people within the Imperium. For the greater good and the defence of all the Emperor has created, they dictate that each moment of a citizen's waking life be filled with labour, prayer, and punishment. They believe that a Human mind left to reflect on anything else is liable to wander toward selfish thoughts and desires. To guard against the influence of the Ruinous Powers, whose use these thoughts as the crack through which they can claim a mortal soul, this cannot be allowed.There is a risk in this approach to order, for from it Chaos is easily born. The merciless attentions of adepts, the harsh laws of planetary governors, and other agents of Imperial laws have turned many who would otherwise never have embraced Slaanesh. A mind overwhelmed with hardship and unrelenting burden has no time for thoughts of sin, but when a moment does come, fleeting though it may be, it stands out against the darkness of life as a burning candle of possibility. For many who stray, sin is not an act undertaken for the sake of rebelliousness, but rather as a way to find relief -- relief from constant struggle, relief from dogmatic rules, relief from restraint. It is this relief that Slaanesh offers in over-generous amounts.It is not just the downtrodden people of the Imperium who feel the crush of hardship in a bleak and foreboding galaxy. War is a constant presence across the stars. Limitless numbers of beings compete for limited resources, creating conflict and strife everywhere. There are even Humans who exist on the fringes of Imperial rule for whom life is little better than if they were fully under its yoke.The harshness of life in the Imperial centre is overwhelming, but it does at least offer a modicum of safety compared to frontier existence. Life is hard and cruel everywhere in the galaxy, and any chance to feel some comfort is very difficult to resist, a fact the Dark Prince exploits to its advantage at every opportunity. A bit of kindness, a moment of joy, is often all it takes to set a soul on the path of damnation. It is not just a reprieve from suffering that lures so many toward their doom in the wicked embrace of the Prince of Pleasure. Comfort is but one sensation in a myriad of possibilities. What of those who, like the Aeldari of old, have experienced what it means to live a life of luxury?Removed from the harshness of daily torment that so many others suffer with, people with the time and the means often find experimentation appealing. The finest foods, the most exotic incense, musical performances from ancient peoples long extinct -- those with the wealth, time, or will to do so can procure all this and more.Yet obsession is not the exclusive province of the wealthy or powerful. A mind and body with no access to luxury can take delight in things that more prosperous individuals would never even notice. Something as simple as the sound of wood crackling in a fire, or the sight of drool forming patterns as it soaks into cloth, or even the taste of freshly cut fingernails can be the focus of an obsession.All that is required is a desire for more and a willingness to put aside restraints and limits. Neighbouring homes are made from plenty of wood that can burn, and the people inside them have mouths filled with drool that can be coaxed out, and fingers that have plenty of nails to eat. It is a simple thing to indulge, especially once all attention is given over to the obsession and other regards are ignored.Regardless of the craving, though, there are limits to how far a mortal can take their obsessions. There are actions and sensations that only a dark mind aided by powerful allies can experience. For instance, with the right mutations, fingers can become ethereal tentacles able to pass through the skull and absorb the pleasurable memories of others directly.Given the right ritual devices infused with Warp energy, a bold mortal can distil the fears of a tortured captive and create an exquisite libation not found in even the richest banquet hall.In exchange for as trifling a thing as a soul, a person can be given the power to be able to heal any wound instantly, allowing them to live over and over again through the experience of cutting out their own organs.All these sensations and so very many more are open to those with the desire to embrace obsession through service to the Master of Excess.
