Sword and the Stars Addenda (from SPI)

[21.38]  (addition)  When the DraKa enter play, the Tech Level of
Harvest is immediately raised to three.  Should the level ever fall
below 3, it is increased by one at the beginning of each Round
until it again reaches three.  When the DraKa leave play, the Tech
Level of Harvest is immediately reduced to a level of -2.

[15.4]  Intercepting by Stargate (optional rule)

A player may intercept *any* enemy Raid or Conquest Operation
attempted anywhere on the map so long as the Intercepting Player
owns a StarGate which is located on his Seat System and the Seat's
Tech Level is 2 or 3 and his Military Sector is 5 or 9.  More than
one player may intercept the same operation (see 15.31).

Note:  A player who uses a StarGate to Intercept may not expend
more resources in this Operation than the combined sum of his
Military Sector Level and the Tech Level of his Seat system.
