Sii Advancement:
There are three ways to advance within the guild.
The first is by gaining guild experience and advancing your control levels and your corresponding military rank. With this increase in rank comes increased responsibility. (see "siihelp millendium")
Once you feel complete at your current control level, you should visit the meditation chambers to meditate upon your experiences.
The second way to advance is to gain other types of experience to invest in training skills. (see "siihelp skills")
The final way to advance in the guild is through the ranks of guild masters. For more info, see "siihelp gms".
