I wish to thank you for all your comments - created quite a stir:)Didnt answer my question though.
4.3 Factions are free to restrict or not restrict access to their home systems and tax players who enter home system. Access to systems that surround home system must not be restricted unless there's a war with another faction.
I do not see many Blood Dragons flying the sigma systems.
If you are saying that you may persue your quary into systems where you do not hold the faction - please say so. As traders we have little enough chance of escaping as it is - where is the line drawn ?
