Gellar Field

A&#160;geller field is a barrier that creates a psy&#160;shield around a ship to protect it from the&#160;warp without it the ship and the crew would be&#160;eaten by the&#160;daemons&#160;that dwell there&#160;and as such must be active at all time but if a ship were full of holes&#160;they would have to be sealed before the jump so nothing&#160;could find its way into the ship&#160;tho it is said that a grey knight ship blesed and&#160;with a full company&#160;may be able to make a short warp jump&#160;but it is critasized that&#160;it would only work if the&#160;grey knight&#160;might "being the&#160;bane of daemons" if there minds where spead bosting the ships wards since only more powerfull daemons would dare to try and fight a grey knight on one of there one battle barge's because of the sheer amount of faith the grey knights have and an unbreakable soul of pure faith it would be like a mortal man diping his hand in moltern lava for a grey knights touch&#160;is poisen to the unfaithfull.
