Vassal
Background
Vassals and Lord are complement to each other in form of military reinforcement, financial and information. Lord requires vassals in order for him to expand the empire.
What are Vassals
A lord can commands a couple of vassals under him/her. Vassals can organize reinforcements to help defend his/her lord. To do this, vassals can build reinforcement ships in `Outpost`.

How to gain Vassals
There are two ways you can get vassals. A free way of getting vassals is to ask your friends to signup using your Vassal link. To get your Vassal link, click on Diplomacy > Vassal. Your vassal link will look something like this http://uc1.GamesTotal.com?tft=xxx

Now the other way to get vassals is to approach another empire and ask them to accept your vassal invitation. The more planets an empire have the more honors it will require to make this empire your vassal. If the person accepts your vassal invitation then he/she will receive honors from you. To check on how to gain more honor, please refer to Diplomacy > Honors in the manual.
To do this, go to Military > Intel and find for an independant empire, then click on vassalize. This will prompt the system to send a vassal offer to that empire. Remember to send a `Private Message` to remind this empire of your offer, and if they accept to click `accept` in the Diplomacy > Lord page. It will cost you `Planet x 10` honors for each empire depending on the planet size, if you do not have sufficient honors to vassalize those empires then the vassalize offer will automatically fail.
