Time

Time is an important factor within this world, which affects many aspects of gameplay

Day/Night cycle
One full day/night cycle in this world takes 12 hours in real time.

Every Cycle
Once every 12 hour cycle, the following things are recalculated:


 * Locations you have not visited within that day degrade slightly on your map (unless you have the relevant Skills)
 * Unused skills not within your affinity lose a small amount of XP/levels

Sleeping
Sleeping at some point every 12 hour day is beneficial for a number of reasons.

Benefits

 * After any period where you have slept at least 4 hours, you receive a buff of some sort for the next 4 hours.\

Penalties

 * After any period where you have not slept for 8 hours or more, you receive a debuff of some sort that applies (and maybe stacks more every hour?) until you do sleep.
